ES280503U - Safety lock (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Safety closure, essentially characterized by being constituted from a base body in which an axial hole is established which has at its ends and through respective straight steps, respective sectors of greater diameter, one of them in correspondence with the bolt itself said, established as a single piece on one of the ends of said rod, and another intended for the coupling of a locking button, fixed to the opposite end of the rod, with the particularity that between said blocking button and the corresponding step of the hole axial, an expansion spring is established that tends to project said push-button outwards, and consequently to keep the bolt in a retraction or inoperative situation, having provided that in the same body a second drill is installed, this diametral and secant of the previous one, closed by one of its ends, in which the associated arm is established in turn or to a side unlocking pushbutton, with the particularity that said arm incorporates a hole through which the piston rod of the bolt is passing and which coincides dimensionally with the diameter of the latter, it being further provided that said rod incorporates a perimetral throat that when the device is blocked, it faces the bore of the arm and determines the locking in such a situation by radial displacement of said arm due to the effect of a recuperating spring.
